shows that it does not work out of the box, but reports that it can be made to work ...

Quote:

The ov511 driver included with the kernel loads, but neglects to load the image decompressor kernel module.
This is evidenced in dmesg by the line "No decompressor available."

To get things running, load the kernel module "ovcamchip" at startup.
Driver home page is http://alpha.dyndns.org/ov511/,

and problem solution is from https://www.redhat.com/archives/fedora-list/2004-July/msg03162.html

This didn't work for me I then found

http://alpha.dyndns.org/ov511/install.html

And modified /etc/modules.conf appending the line

above ov511 ov511_decomp

to load the ov511_decomp module above ov511

However, inspection of /lib/modules/2.6.25.16/kernel/drivers/media/video/ does not reveal any ov511_decomp module?

I downloaded the kernel source and it is not in there either. The source from the http://alpha.dyndns.org/ov511 - the site of Mark McLelland who wrote the driver originally - is quite different from BK's patched source for the 2.6.25.16 kernel...

I should add that I tried blacklisting the ov511 module and adding the gspca module to see if that did the trick but sadly no.

Would appreciate any thoughts on how to proceed? Or anyone who has made such a beast behave!!

inspection of /lib/modules/2.6.25.16/kernel/drivers/media/video/ does not reveal any ov511_decomp module?

I think that's only relevant to older versions of the ov511 driver.
With recent versions of the ov511 driver, compression support is built into the driver ...
... but you may need to force it ON. So open /etc/modprobe.conf in Geany, and add this line -

Code:

options ov511 compress=1

Reboot.
Check your diagnostic messages, and if still no success, it might be worth loading the ovcamchip module as suggested in the kubuntu link you found. Open /etc/modprobe.conf again. Leave the last line we added (it won't hurt) and add another line -

Code:

install ov511 modprobe ovcamchip; modprobe --ignore-install ov511

Reboot.

And when you try XawTV, be aware that your WinTV PVR-150 is /dev/video0, so you will probably need to specify /dev/video1, like this -

I have another puppy box (4.2.1) without the Haupauge WinTV card (to rule out any conflicts) this machine is old AMD Duron that would have been dumped but for puppy - the USB webcam is detected as before as an OmniVision -vendor 0x5a9 - productID 0xa518 - the ov511 module is loaded.

I tried editing /etc/modprobe.conf appending the line

Code:

options ov511 compress=1

rebooted - and ran :

Code:

xawtv -c /dev/video0

and ran into the same error in the first post - selecting a device in xawtv is not possible there are no video devices available to select.
So I edited /etc/modprobe.conf again and added

could be way off base - there is some trial and error going on here and hoping someone can put me right... please. It still won't work with the same message from xawtv. xawtv and Skype shows the device - OV518+ USB Camera - all looks to be well it just doesn't work. Hey maybe the camera is buggered? The light is on, on the camera as though someone is home...
